Key result
Postpartum renal cortical necrosis and peripartum cardiomyopathy co-occur after hemorrhage, suggesting a shared endotheliopathy.
Why the study?
Renal cortical necrosis and peripartum cardiomyopathy are linked to endothelial dysfunction, yet their coexistence has rarely been reported.
Case Report (n=1)
No
Highlights the rare coexistence of renal cortical necrosis and peripartum cardiomyopathy, emphasizing that persistent oxygen requirement despite fluid removal should prompt early cardiac assessment.

Postpartum renal cortical necrosis with persistent hypoxia may prompt cardiac evaluation; leaves open whether routine screening alters management.
A 36-year-old woman developed postpartum haemorrhage after an uncomplicated vaginal delivery, followed by disseminated intravascular coagulation, thrombotic microangiopathy, and persistent anuric kidney failure. Contrast-enhanced computed tomography showed bilateral reversal of corticomedullary enhancement, consistent with renal cortical necrosis. Despite kidney replacement therapy and 13 litres of ultrafiltration, she remained oxygen-dependent, prompting cardiac evaluation on postpartum day 11, which revealed severe left ventricular systolic dysfunction (ejection fraction 25%) consistent with peripartum cardiomyopathy. Cardiac function recovered with medical therapy, whereas kidney function remained irreversible, requiring dialysis and transplantation. Renal cortical necrosis and peripartum cardiomyopathy are linked to endothelial dysfunction, yet their coexistence has rarely been reported. Cardiac dysfunction emerged only after substantial fluid removal, arguing against volume overload alone and suggesting a shared postpartum endotheliopathy. Persistent oxygen requirement despite adequate decongestion should prompt early cardiac assessment rather than being attributed to fluid overload alone.

Vanoost et al. (2026) conducted a case report in Postpartum hemorrhage complicated by renal cortical necrosis and peripartum cardiomyopathy (n=1). Postpartum hemorrhage was evaluated. A 36-year-old woman developed bilateral postpartum renal cortical necrosis and peripartum cardiomyopathy after postpartum hemorrhage, suggesting a shared postpartum endotheliopathy.
